Picking up an old Bracket car. Have some questions

I picked it up tonight. It is in better shape than I expected. It has had a few upgrades since I saw it last. It has an msd 7AL. It now has an alternator on it which was needed for the msd. The one slick did not hold air but they are fairly new looking. The front wheels have been replaced with a small bolt pattern mag wheel with skinny Tires. It started and ran very easily. Pulled right onto the trailer. Seat belts have also been replaced since I sat in it last. Can't wait to play with it.
